Monster Hunter Rise.
For years a new MH game for Switch had been a dream of mine that felt like it would never come true, and now that it has, its everything I hoped for; amazing creature designs, thrilling combat, incredible depth and breadth of content, and a brilliantly addictive and rewarding loop of hunting to upgrade and upgrading to hunt that provides a near endless stream of endorphins.
Not just the best game of 2021, but quite possibly my favourite game since BOTW back in 2017.
